1. What is machine-made sand?

Machine-made sand is usually made of river pebbles, cobblestones, granite and other stones through machine-made sand production lines. Compared with natural sand, machine-made sand has more uniform particle shape and strong plasticity. Therefore, it is widely used as raw materials in important fields such as highway, railway construction and concrete mixing stations.

2. Process flow of machine-made sand production line

The machine-made sand production line system consists of coarse crushing (jaw crusher) - pre-screening (vibrating screen) - medium crushing (impact crusher or cone crusher) - sand making (high-efficiency sand making machine) - screening and washing (sand washing machine) - semi-finished product yard and finished product yard.

The stone is evenly fed into the jaw crusher for coarse crushing by a vibrating feeder, and then transported to the sand making machine by a belt conveyor for further fine crushing. The finely crushed material is screened by a vibrating screen, and the qualified part enters the sand washing machine for cleaning, and finally sent out by the finished product conveyor belt to become a finished product.

Materials that do not meet the requirements of the finished machine-made sand particle size are sent back to the sand making machine by the belt conveyor for reprocessing, forming a closed loop for multiple times. The particle size of the finished product can be combined and graded according to the user's requirements.

3. How much does a machine-made sand production line cost?

The investment in a machine-made sand production line is affected by many factors. The price is different depending on the output. The output of 200 tons per hour and 300 tons per hour are definitely different. Generally, the higher the output, the more expensive the price. In addition, the equipment models selected by customers are different, and the prices of the same equipment are also different from different manufacturers. Generally, the investment in a machine-made sand production line ranges from hundreds of thousands to millions.
